Where does sagan come from?
The unit is derived from the phrase "billions and billions (of stars)", erroneously attributed to the American astronomer Carl Sagan. The lower bound of such a number must be two billion plus two billion, or four billion. Johnny Carson popularized the phrase through his occasional impersonation of Sagan throughout his career.
